Configuring T1/E1 Unstructured Circuit Emulation Services
To configure a hard PVC for unstructured CES, follow these steps, beginning in privileged EXEC mode:
Example
The following example shows how to configure the hard PVC for unstructured CES (shown in
Figure 19-1):
CESwitch# show ces status
Interface IF Admin Port Channels in
Name Status Status Type use
------------- -------- --------- ----------- -----------
CBR3/0/0 UP UP T1
CBR3/0/1 DOWN UP T1
CBR3/0/2 DOWN UP T1
CBR3/0/3 UP UP T1
Command Purpose
Step1 Switch# show ces status Displays information about the current CBR
interfaces.
Use this command to choose the source CBR
port.
Step2 Switch# show atm status Displays information about the current ATM
interfaces.
Use this command to choose the destination ATM
port.
Note The interface must be up.
Step3 Switch# configure terminal
Switch(config)#
At the privileged EXEC prompt, enters global
configuration mode.
Step4 Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the physical interface to be configured.
Step5 Switch(config-if)# shutdown Disables the interface.
Step6 Switch(config-if)# ces aal1 service {structured |
unstructured}
Configures the CES interface AAL1 service type.
Step7 Switch(config-if)# ces aal1 clock {adaptive | srts
| synchronous}
Configures the AAL1 clock mode.
Step8 Switch(config-if)# ces circuit circuit-id
circuit-name name
Configures the CES interface circuit identifier
and circuit name.
Note For unstructured service, use 0 for the
circuit identifier.
Step9 Switch(config-if)# ces pvc circuit-id interface
atm card/subcard/port vpi vpi vci vci
Configures the hard PVC to the ATM interface
and VPI/VCI.
Note The VPI/VCI are arbitrary here. They are
not fixed, whereas the VPI/VCI described
in General Guidelines for Creating
Soft PVCs for Circuit Emulation
Services, page 19-7 are fixed.
Step10 Switch(config-if)# no shutdown Reenables the interface.
